Just switched to Moon Reader because I like that it's customizable. I copied my folders from calibre onto my sd card and everything was imported okay except that I noticed that on some books, the cover is wrong. For example, one of my Nora Roberts books as the cover in Spanish. It's not the way in Calibre. Should I be copying the books only and not the metadata?

I have a Samsung Galaxy Tab 2, 10.1. I don't know if that info is helpful or not.
